Abstract
This paper describes the experimental investigation of a five-staged tidal flow
reed bed system for the treatment of an agricultural wastewater from a pig farm.
In particular, study focuses on the start-up of the reed bed treatment process.
Initial investigation was concerned with batch operation of the system with
addition of an artificial nutriment, commercial baby bio, to promote growth of
the reeds; emphasis was placed on how to establish a healthy microorganism
population within the bed matrix, i.e. period in which plants and microbes adjust
to the hydrological conditions of the new living environment. Thereafter, diluted
pig slurry was introduced into the reed bed system that adopted a novel operation
of 'tidal flow'. Strength of the influent was
